Abstract (en)
[origin: US2011151934A1] The present invention provides an automatic keypad unlocking method and apparatus for mobile terminal, so as to automatically unlock a keypad when the mobile terminal is to be used. The apparatus includes: a state detecting unit configured to detect a stress state or a motion state of the mobile terminal, to recognize whether the mobile terminal is in a hand-held state based on the stress state or the motion state, and to generate a triggering signal when the mobile terminal is recognized as in the hand-held state; a camera configured to receive the triggering signal, and to capture image based on the triggering signal; a face detecting unit configured to detect a facial image from the image captured by the camera, and to generate an unlock control signal if the face detecting unit determines that a facial image of predetermined scale size is contained in the captured image; and an unlocking unit configured to receive the unlock control signal, and to automatically unlock a locked keypad based on the unlock control signal. The present invention automatically unlocks the keypad by recognizing the hand-held state of the mobile terminal.
